Changing the font size on Xiaomi smartphones is one of the most popular settings among users with visual problems or those who want to optimize the display of text to their preferences. Depending on the version of MIUI (Xiaomi’s Android shell) and the device model (Redmi Note 12, POCO X5, Mi 13, etc.), the process may be slightly different, but the general logic remains the same. In this article, we will analyze all the current methods, from standard settings to advanced methods using ADB and third-party utilities.
It's important to understand that changing the font affects not only readability but also the location of interface elements. For example, on the Xiaomi 13 Pro with MIUI 14, too large a font can "break" the display of some menus in applications, and on the Redmi 10A with a budget screen, small text will become illegible. We will tell you how to avoid typical errors and choose the best options for your device.
Method 1: Standard MIUI settings (for all models)
The easiest and safest method is to use built-in shell tools. It is suitable for 99% of Xiaomi devices, including the latest models from 2023-2026 (POCO F5, Redmi Note 12 Pro+, Xiaomi 14, etc.). The interface may vary slightly depending on the version of MIUI, but the algorithm of actions remains the same.
To change the font size:
- Open the Settings app (the gear icon on the home screen).
- Go to the Screen section (or Additional settings → Screen on older versions).
- Select Text Size (sometimes called Font Size).
- Adjust the size with the slider. Available values usually range from 80% (minimum) to 130% (maximum).
- Click Ready or Apply to save the changes.
On some devices (e.g. POCO M5), you can change the font style on the same menu to choose between standard MI Sans, Roboto or other pre-installed options, but text size and style are customized independently.
⚠️ Attention: On devices with MIUI for POCO (for example, POCO X4 Pro) the path to font settings may be different. If you can't find the Screen section, try going to Settings → Special facilities → Visual corrections.
Method 2: Scaling the screen (affects the font and interface elements)
If you want to zoom in not only text, but all interface elements (icons, buttons, menus), use screen zoom. This is useful for users with visual impairments or when using a smartphone as a screen. GPS-However, note that if you zoom in, some applications (such as games or banking) may not display correctly.
How to scale up:
- 📱 Open the Settings. → Screen. → Screen size (or Display size).
- 🔍 Choose one of the preliminary options: Small, Standard, Large, Very Large.
- 🔄 If you need precise settings, activate the User Scale option and move the slider.
On Xiaomi 12T and newer on this menu, you can also adjust the pixel density (DPI) - the parameter responsible for the number of dots per inch. By default, the value is 440 DPI, but it can be reduced to 380 DPI for a more compact display or increased to 560 DPI for improved readability.
| Parameter | Minimum value | Standard value | Maximum value |
|---|---|---|---|
| Type size | 80% | 100% | 130% |
| Screen size | Small (85%) | Standard (100%) | Very large (150%) |
| DPI density | 380 | 440 | 560 |
💡
If after rescaling some applications (such as SberBank Online or VKontakte) are not displayed correctly, try resetting the settings only for them. To do this, go to Settings → Applications → Application Management, select the problematic application and click Reset Settings (not to be confused with deleting data!).
Method 3: Use of the "For the Visually Impaired" mode (increased contrast + font)
For users with severe vision problems, MIUI has a special mode that not only increases font, but also improves text contrast, makes buttons larger and makes navigation easier, which is useful for older people or those who use a smartphone in poor light conditions.
How to activate the mode:
- Go to Settings → Special features → Visual corrections.
- Select Mode for the visually impaired (or large text on some models).
- Activate the switch and adjust the settings: 🔤 Font size – up to 200% of the standard. 🎨 Contrast text – makes the letters bolder and clearer. 📱 Simplified interface – removes unnecessary elements from the screen.
On Redmi 9A and other budget models, this mode can slow down the interface slightly due to additional graphics processing. If you notice lags, try turning off the interface animation option in the developer settings (Settings → About Phone → MIUI version – press 7 times to unlock).
What if the regime for the visually impaired is not maintained?
Method 4: Install third-party fonts via MIUI Themes (for advanced users)
If you don’t like standard fonts in MIUI, you can install custom options through the official Themes app, which works on most devices, except for some regional firmware (for example, for Xiaomi for Russia with limited themes).
Installation instructions:
Upload the font file (.ttf) to your device |Open the Themes app |Go to Profile → My Themes → Fonts |Click Import and select the file |Apply the font and restart the device-->
Popular font sources for Xiaomi:
- 🌐 Google Fonts – Free Library with Cyrillic Support.
- 📱 Official catalogue of topics MIUI (Xiaomi account requires).
- 💾 Forums 4PDA — Topics with Russified fonts for specific models.
⚠️ Note: Installing fonts from unverified sources can lead to system crash (bootloop) on devices with a high-quality system. MIUI 13/14 Because of the strict file signature checks, back up your Settings before you install them. → Additionally. → Backup.
On the POCO F4 GT and other devices with a Snapdragon 8 Gen 1 processor, custom fonts may not apply to system applications (such as Calls or Messages) due to manufacturer limitations, in which case only root or ADB will help.
Method 5: Change the font through ADB (for power users)
If standard methods don’t work (e.g., you need to set a font size of 150%, which is not available in the settings), you can use Android Debug Bridge (ADB), which requires connecting your smartphone to your computer and basic command line knowledge.
Step-by-step:
- Activate Developer Mode: Settings → About Phone → MIUI Version (click 7 times)
- Enable USB debugging in Settings → Additional → For developers.
- Connect your smartphone to your PC and execute the commands: adb shell settings put system font_scale 1.5 (where 1.5 — desired scale, for example, 1.2 for 120%).
- Reboot the device: adb reboot
Permissible values for font_scale:
- 0.8 – 80% (minimum size)
- 1.0 - 100% (standard).
- 1.3-130 percent (maximum in settings)
- 1.5-150 percent (available only through ADB)
💡
Changes to ADB are applied to ALL applications, including system ones. If the text gets too large and the interface gets broken, reset to 1.0 by the same command.
Problem Solving: The font does not change or is reset
Sometimes users find that the font settings are not saved after a reboot or apply to individual applications. Let's consider the typical reasons and ways to eliminate them.
Problem 1: The font is reset after the MIUI update.
- 🔄 Check if the settings have been reset in the settings → Additionally. → Resetting settings → Resetting interface settings.
- 📥 If the update was “dirty” (without a Wipe), reset the cache in Recovery (click Power). + Volume up when switched on).
Problem 2: Some apps (like Telegram or YouTube) don’t change the font.
- 🔧 Check the settings of the application itself – many messengers and social networks have their own text size parameter.
- 🛠️ If you use a dark theme, try switching to a light theme – sometimes this solves the display problem.
Problem 3: Xiaomi has no global firmware font settings section.
- 🌍 Install regional firmware (for example, MIUI Europe via Fastboot or Recovery.
- 🔗 Use it. ADB (described in Method 5).
